Question

Pod kornem(2x+0.8) = 2

Answer 1

√(2x+0.8)=2
2x+0.8=4
2x=3.2
x=1.6

Answer 2

To find the root of the equation "Pod kornem(2x+0.8) = 2," we can solve for x by isolating the expression within the square root. Let's go through the steps:

1. Start with the equation: Pod kornem(2x+0.8) = 2

2. Square both sides of the equation to eliminate the square root: (Pod kornem(2x+0.8))^2 = 2^2

   This simplifies to: (2x+0.8) = 4

3. Subtract 0.8 from both sides: 2x = 4 - 0.8

   Simplifying further: 2x = 3.2

4. Divide both sides by 2 to solve for x: x = 3.2 / 2

   This gives us the solution: x = 1.6

Therefore, the root of the equation "Pod kornem(2x+0.8) = 2" is x = 1.6.
